There is a difference between "exposure" and enabling.
The stance is I will not lie nor cover up your A. If asked I will tell the truth. I have the right to discuss my sitch with whomever I want, whenever I want.
That's the stance and it need not be articulated.
To do otherwise is enabling.
This is entirely different from telling the world, her boss, OM other half or announcing it on FB.
If asked you can say "we separated because WW is having an A with scumbag featured slime ball grot features. Yes and she is working from home gives her more scope for dropping her knickers"
Put together your story it will help you and cut short any manipulation on her side.
If she asks you simply say "I am not going to lie about why we are S"
Well done in getting back in your home and the MBR.
